How to Control the Backlight on a Laptop
Most laptops now have the Windows Vista operating system, even with the newer Windows 7 out. Windows Vista on laptops lets you choose your lighting settings on the laptop to preserve battery power. If battery power isn't a concern, maybe your eyes are straining while staring at the laptop, and darkening the screen would ease that strain. The light settings on a laptop are customizable, so you can make it suit your personal needs.
Enter the "Start" menu at the bottom of the screen, and click on "Control Panel."
Click on "Mobile PC," then enter the "Power Options."
On the left side, select "Adjust the display brightness."
Use the slide bars to adjust the backlight brightness. There are two different slidebars: one for when the laptop is only using the battery, and another for when the laptop is plugged in.
Select "System Preferences," then choose "Displays."
Use the slidebar at the bottom to adjust the brightness of the screen.
You can also select to have the laptop automatically adjust the screen depending on the light changes around you.
Tips & Warnings
- Another way to adjust the screen on your laptop is by holding down the "Function" key and using the arrow keys. This will vary from laptop to laptop, however.
